Helios AMW 225/4

Medium-pressure duct fan with a cylindrical duct casing and flanges on both sides, directly driven. The cylindrical duct is made of galvanized steel sheet and features formed flanges on both sides as well as a hole pattern according to DIN 24155 Sheet 3, with an integrated guide vane. The axial impeller is made of plastic and has 14 spatially curved blades. It operates without vibrations due to dynamic balancing according to quality level G 6.3 VDI 2060 and DIN ISO 1940. The fan is equipped with a single-phase AC capacitor motor in a closed design, which is maintenance-free and has thermal contacts integrated into the winding. The speed can be controlled by voltage reduction, and it features sealed, low-noise ball bearings with long-term lubrication, making it non-reversible.
